I'm on Nadia x64 (14.1), managed to mount the drive in RW mode (had to disable journaling and give everyone RW access on it on my iMac first). I can share it via SMB or can share other folders over NFS, but this one doesn't work: I get "does not support nfs export" for it.

Additional info - from what I googled, in order to have NFS export support for HFS+ partitions, hfsplus support needs to be compiled into the kernel - and in the case of Nadia (14.1) it seems to be, by default.

Is there any way I could force NFS to export it, since the OS can read / write to that partition?
